ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 229390 - KFD2-SR2-EX1.W Intrinsic Safety Barrier
This K-System intrinsic safety barrier provides galvanic isolation and signal conditioning for two-channel switch inputs originating from hazardous areas. It converts NAMUR sensor or dry contact signals into safe area relay outputs, ensuring explosion protection according to Ex ia IIC standards. Engineered for DIN rail mounting, it integrates seamlessly into process control systems requiring certified safety integrity for field device interfacing.
